what mixture goes into h/e
people say water wetter, 50/50 dex cool/water, 50/50 water wetter/water. What is the correct mixture? Also I have seen the diagram for the h/e install, but wondering if it hooks up to the stock h/e or the radiator? I know alot of people call h/e's radiators and vice versus.

I'm running 50/50 water/dexcool.
This is how I installed it with my stock heat exchanger. IAT2s go up to 130-ish after afew wot pulls, but never go over 109 while cruising...
This is how I installed mine:

Nobody really said if it should go to the aftermarket h/e first or second...

50/50, but I have an 80/20 mix in mine with a dash of water wetter. I noticed a nice drop in IAT2's when I did this. Also, the 80/20 mix is safe for anything above 17*F. If you don't drive your car in the winter months (like me) it's a great mixture, because it still provides some freeze protection. If you drive your car year round keep the mixture at 50/50.

Doesn't what you put in it mix with the other h/e? Why would I put a whole shitload of water? 50/50 sounds good to me with a little water wetter. What does your guys coolant temps look like? Same?

GM Racing uses straight distilled water w/ 1 bottle of water wetter. The water wetter helps with cooling, but its used more as a lubricant in this situation.
seriously though it would be hard to get those exact measurements.. I guess rough estimate. right? My h/e you cant fill it, it doesnt have a filler on it, so I filled it from the thing in front by the sc.
